efi_loader: GetTime() must return EFI_UNSUPPORTED

2019-06-14T17:18:40Z

If the GetTime() runtime service is not supported, EFI_UNSUPPORTED has to be returned. Signed-off-by: Heinrich Schuchardt

efi_loader: add RuntimeServicesSupported variable

2019-06-14T17:18:40Z

This variable is defined in UEFI specification 2.8, section 8.1. Its value should be updated whenever we add any usable runtime services function. Currently we only support SetVirtualAddress() for all systems and ResetSystem() for some. Signed-off-by: AKASHI Takahiro Reviewed-by: Heinrich Schuchardt

efi_loader: event signaling in ExitBootServices

2019-06-10T21:06:19Z

ExitBootServices() has to stop timer related activity before calling the events of the EFI_EVENT_GROUP_EXIT_BOOT_SERVICES event group. But our current implementation was stopping all other events. All events have to observe the task priority level. Signed-off-by: Heinrich Schuchardt

efi_loader: Kconfig entries for GetTime(), SetTime()

2019-06-01T02:53:13Z

The GetTime() and the SetTime() runtime services are not obligatory. So let's make them customizable. Signed-off-by: Heinrich Schuchardt

efi_loader: handling of daylight saving time

2019-05-31T21:27:20Z

If SetTime() is meant to set daylight saving time it will be called with Time.Daylight == EFI_TIME_ADJUST_DAYLIGHT | EFI_TIME_IN_DAYLIGHT. Return 0 from GetTime() if time is not in daylight because we cannot determine if we are in a time zone with daylight saving time. Signed-off-by: Heinrich Schuchardt

efi_loader: check time in SetTime()

2019-05-31T21:27:12Z

The UEFI spec prescribes that we check that the timestamp passed to SetTime() is checked for validity. Signed-off-by: Heinrich Schuchardt

efi_loader: return values of GetTime()

2019-05-24T16:58:13Z

According to the UEFI spec 2.8 the GetTime() runtime service should return EFI_UNSUPPORTED if the real time clock is not available. Signed-off-by: Heinrich Schuchardt

efi_loader: implement SetTime

2019-05-24T16:58:13Z

Implement the SetTime() runtime service. Extend the real time clock selftest to check setting the clock. Signed-off-by: Heinrich Schuchardt

efi_loader: efi_add_runtime_mmio()

2019-02-13T08:40:05Z

The first parameter of efi_add_runtime_mmio() is a pointer to a pointer. This should be reflected in the documentation. Signed-off-by: Heinrich Schuchardt Signed-off-by: Alexander Graf

efi_loader: Make RTS relocation more robust

2018-12-23T03:02:20Z

While changing the RTS alignment to 64KB in commit 7a82c3051c8f ("efi_loader: Align runtime section to 64kb") the relocation code started to break. The reason for that is that we didn't actually look at the real relocation data. We merely took the RUNTIME_CODE section as a hint and started to relocate based on self calculated data from that point on. That calculation was now out of sync though. To ensure we're not running into such a situation again, this patch makes the runtime relocation code a bit more robust. We can just trust the phys/virt hints from the payload. We also should check that we really only have a single section, as the code doesn't handle multiple code relocations yet.
